CVE-2017-15638: The SuSEfirewall2 package before 3.6.312-2.13.1 in SUSE Linux Enterprise (SLE) Desktop 12 SP2, Server 12 SP2, and Server for Raspberry Pi 12 SP2; before 3.6.312.333-3.10.1 in SLE Desktop 12 SP3 and Server 12 SP3; before 3.6_SVNr208-2.18.3.1 in SLE Server 11 SP4; before 3.6.312-5.9.1 in openSUSE Leap 42.2; and before 3.6.312.333-7.1 in openSUSE Leap 42.3 might allow remote attackers to bypass intended access restrictions on the portmap service by leveraging a missing source net restriction for _rpc_ services.
The exploitability of CVE-2017-15638 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2017-15638 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2017-15638, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2017-15638, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.252% (probability of exploit)
EPSS Percentile: 64.96%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 35.040000000000006% of others.
